Staying up-to-date with filter changes is important for the life of Nilfisk Vacuums. Our latest DIY video features detailed instructions to properly change the Nilfisk VHT EXP filter.
- HEPA and ULPA filters should be changed each year.
- Main filters should be replaced every 6 months to 1 year.
- Microfilters (used on GM and IVT models) should be changed every 3 months or when discoloration is noticeable.
Pay close attention to the vacuum’s indicators, if so equipped. Manometer dials or LED lights reading in the red indicate that the filter needs to be serviced, purged, replaced or there is a blockage upstream.
